Technical Need flathead schooling

I've never driven a car with a flathead or ever even heard a car with a flathead. Please tell me the pros and cons of one? The only two things I've ever heard is they sound really neat and tend to overheat.Thanks.

 

Flathead you say? Doesn't ring a bell housing. This is mostly a Small Block Chevy site.

 

Running hot is a myth. They will run forever as long as you keep oil and water in them and make plenty of power for an early ford. Down fall is price. If you can find a decent runner you'll be ok... rebuilding one gets pricey quick. There's guys who drive them cross country and daily them. Just an engine when it comes down to it.
